' SPECIFICATION forming part of Letters Patent No. 727,956, dated. May 12, 1903.

Application filed May 3, 1902. Serial No. 105,867. (No model.)

This invention relates to new and useful improvements in draft-equalizers; and the essential purpose of the same is to provide a device involving a minimum number of parts and which may be adjusted for use with either five or six horses. The equalizer is especially adapted for attachment to gang-plows and harvestermachines, and the draft attachments are disposed so as to distribute the positions of the animals.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible ofmodification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure l is a top plan view showing the parts arranged for use as a five-horse evener. Fig. 2 is a longitudinal sectional view of the device, whiftletrees not shown.

Corresponding and like parts are referred to in the following description and indicated is disposed at the end of the draft-lever opposite that upon which the equalizing-lever is disposed, and this clevis isada'pted to connect a doubletree' to thedraft-lever. The equalizing-lever is fulcrumed intermediate its ends, and a singletree 5 is adapted for conlever.

openings 9 are also provided upon the draftlever, by which the point of fulcrum for the said draft-lever in its connection with the harvesting-machine or plow or other implement may also be adjusted.

When the equalizer is used for a six-horse evener, the fastening by which the equalizing-lever 3 is pivoted to the draft-lever is adj usted so as to pass through the openings in the spaced members 3 and 3 of the said equalizing-lever nearestthe inner ends thereof. Also the fastening by which the clevis 2 is secured to the draft-lever 1 is adjusted so as to pivot the lever through the opening nearer the end of the draft-lever upon which the equalizing-lever is'disposed. The points of fulcrum beingarranged as above explained, any ordinary means for adapting three horses to the draft-bar 6 may be utilized, and the equalizer may be thus adapted for use as a six-horse evener. The spaced bars of the equalizing-lever are disposed upon opposite Openings 8 upon the draft-.

sides of the draft-lever, bringing the several parts of the device in approximately the same plane, this being of importance in this class of devices.

The arrangement'of-theseveral parts is such that the animals are disposed with relation to the equalizer in positions in which they cannot in any way be impeded in their movement by each other, which is deemed an essential advantage for the special disposal of the said parts.

Having thus described the invention, what is claimed as new is- In a draft-equalizer, and in combination with a draft-lever 'adjustably fulcrumed intermediate its ends, a doubletree secured to one end of the draft-lever, an equalizing-le- Ver adjustably pivoted intermediate its ends ing respectively secured to the inner ends of [O to the opposite end portion of the draft-lever the spaced bars of the equalizing-lever, and and comprising spaced bars disposed upon adoubletreeztdapted tobesecuredto theaforeopposite sides of the draft'lever, said bars said draft-bar, substantially as described.

having their outer ends brought together, a q singletree secured to the outer end of thel VALLAGE JAMED equalizing-lever, and a. draft-bar comprising In presence ofa single bar bent to form spaced end portions, Jos. A. BEAR,

the spaced end portions of the draft-bar be O. M. ALLEN.
